808929 ÷ 51 
Let's see how many times 51 fits into 808929.

Going ahead to step 1:
If we divide 8 by 51, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 51

Let's proceed to step 2:
51 can be fit into 80 1 times, resulting in a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 29 after subtracting 51 from 80.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 51

Advancing to step 3:
If we divide 298 by 51, we get 5 and a remainder of 43.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 43 after subtracting 255 from 298.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 51

Let's proceed to step 4:
439 divided by 51 is 8 with a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
The remainder is 31 after subtracting 408 from 439.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 51

Step 5:
When dividing 312 by 51, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 1586.0
Subtract 306 from 312 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 51

Step 6:
51 can be fit into 69 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 15861.0
The remainder is 18 after subtracting 51 from 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
180 divided by 51 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 15861.3
Deduct 153 from 180 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
If we divide 270 by 51, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 15861.35
The remainder is 15 after subtracting 255 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
The number 51 fits into 150 2 times, leaving a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 15861.352
Deduct 102 from 150 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
When dividing 480 by 51, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 15861.3529
If we subtract 459 from 480, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
210 divided by 51 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 15861.35294
Subtract 204 from 210 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
51 can be fit into 60 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 15861.352941
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
The number 51 fits into 90 1 times, leaving a remainder of 39.
The next digit of our result is 1. 
Result so far: 15861.3529411
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

In conclusion, the division gives 15861.3529411 with a balance of 3.9e-07.
